Important Safety Instructions

For detailed sprayer information and warnings, see Operation manuals 312001 or 313034 included with Magnum sprayers.

Pressure Relief Procedure

To help prevent injection injuries, follow this procedure when you stop spraying and before you service or clean the sprayer, remove parts, or repair leaks.

1. Turn power switch OFF. Unplug sprayer.

2. Turn Spray/Prime valve to PRIME to relieve pressure. Turn pressure control knob left (counterclockwise) to minimize pressure.

312932A

3. Trigger gun.

4. Put trigger safety in safety ON position.

NOTE: Leave Spray/Prime valve in the PRIME position until you are ready to spray again.

If you suspect that the spray tip or hose is completely clogged or that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the tip guard retaining nut

or hose end coupling to relieve pressure gradually. Then loosen it completely. Clear the tip or hose obstruction.
